The difference in vegetation density in burnt and unburnt Assignment

The difference in vegetation density in burnt and unburnt - Assignment Example In this case, the mean ranks were compared but not the medians. The above table indicate the group with the highest density of plantation, overall; the group with the highest rank. In this regard, the un-burnt area is observed to have the highest density of plantation Basing on the data above, it can be concluded that plantation density in the un-burnt area was not statistically significantly higher than the burnt area(U=2,p=0.4).This implies that further studies need to be done to determine the repeatability of the results in order to confirm if the results are valid. According to literature it is clearly evident that frequent fires might have an impact on the young plants including higher size class (Trollope et al., 1998). The frequency of fire usually determines the length of time the plant is required to recover before the next fire occurs. The slower the rate of recovery, the more likely it is that the composition and structure of the vegetation will be changed, specifically where fires occurs often.
